Subdivide triangles

Subdivide a mesh with congruent and anti-congruent subtriangles

Usage

fmesher_subdivide(
  mesh_loc,
  mesh_tv,
  mesh_boundary,

  subdivisions,
  options
)

Arguments

mesh_loc

numeric matrix; mesh vertex coordinates

mesh_tv

3-column integer matrix with 0-based vertex indices for each triangle

mesh_boundary

2-column integer matrix with 0-based vertex indices for boundary constraints, currently ignored

mesh_interior

2-column integer matrix with 0-based vertex indices for interior constraints, currently ignored

subdivisions

integer; number of new points along each edge.

options

list of triangulation options (sphere_tolerance)

Value

A list of new loc and tv information

Examples

mesh <- fm_mesh_2d(
  boundary = fm_segm(rbind(c(0,0), c(1,0), c(1,1), c(0, 1)), is.bnd = TRUE)
)
new_mesh <- fm_subdivide(mesh, n = 3)
plot(new_mesh, edge.color = 2)
plot(mesh, add = TRUE, edge.color = 1)
